GAabbreviate function issue

[cbain1]

No matter what inputs I use, it seems to give this output

Iter = 94 | Mean = 1.048428 | Best = 1.047688
Iter = 95 | Mean = 1.048798 | Best = 1.047688
Iter = 96 | Mean = 1.049274 | Best = 1.047688
Iter = 97 | Mean = 1.048428 | Best = 1.047688
Iter = 98 | Mean = 1.048899 | Best = 1.047688
Iter = 99 | Mean = 1.048428 | Best = 1.047688
Iter = 100 | Mean = 1.048058 | Best = 1.047688
Error in sign(list.i) : non-numeric argument to mathematical function

Is there something that I am doing wrong?

Thank you!

And what were you doing and with what. What were you expecting as output?

We need to see your original code and some sample data. See

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

FAQ: What's a reproducible example (`reprex`) and how do I create one?

Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it and feel your pain. Then, hopefully, folks can more easily provide a solution. What's in a Reproducible Example? Parts of a reproducible example: background information - Describe what you are trying to do. What have you already done? complete set up - include any library() calls and data to reproduce your issue. data for a reprex: Here's a discussion on setting up data for a reprex make it run - include the minimal code required to reproduce your error on the data…

Error in sign(list.i) : non-numeric argument to mathematical function

is all there is to go on. @jrkrideau is right—that's notmuch.

The error message is complaining that the sign function is expecting a numeric vector and the list.i argument isn't one.

How that came to be is invisible with what can be seen in the OP.
